      Celcius

    Correct Answer
    B. Suhu
    Explanation
    The correct answer is suhu. Suhu refers to the hotness or coldness of an object. It is a measure of the average kinetic energy of the particles in a substance. Termometer is a device used to measure temperature. Derajat means degrees, and Celcius is a unit of temperature measurement.

     Suhu suatu benda diukur menggunakan ....

    • A.

      Barometer

    • B.

      Termometer

    • C.

      Higrometer

    • D.

      Manometer

    Correct Answer
    B. Termometer
    Explanation
    A thermometer is used to measure temperature, which is the degree of hotness or coldness of an object or environment. Therefore, it is the most suitable instrument for measuring the temperature of an object. A barometer measures atmospheric pressure, a hygrometer measures humidity, and a manometer measures pressure of gases or liquids.

    Prinsip kerja termometer adalah ... .

    • A.

      Pemuaian panjang kaca

    • B.

      Pemuaian volume kaca

    • C.

      Pemuaian panjang air raksa

    • D.

      Pemuaian volume air raksa

    Correct Answer
    D. Pemuaian volume air raksa
    Explanation
    The correct answer is "pemuaian volume air raksa." The principle of a thermometer is based on the expansion of the volume of the liquid inside it, which in this case is mercury. As the temperature increases, the volume of the mercury expands, causing it to rise in the thermometer. Therefore, the principle of a thermometer is the expansion of the volume of mercury.

    Pada percobaan tangan kanan masuk ke air panas dan tangan kiri masuk ke air dingin. Ketika kedua tangan dimasukkan secara bersamaan ke air biasa, peryataan yang benar adalah ... .

    • A.

      Tangan kanan dan kiri terasa dingin

    • B.

      Tangan kanan dan kiri terasa hangat

    • C.

      Tangan kiri terasa dingin dan tangan kanan hangat

    • D.

      Tangan kiri terasa hangat dan tangan kiri terasa dingin

    Correct Answer
    B. Tangan kanan dan kiri terasa hangat
    Explanation
    When the right hand is exposed to hot water and the left hand is exposed to cold water, the temperature receptors in both hands send signals to the brain indicating the respective temperatures. However, when both hands are simultaneously exposed to lukewarm water, the brain receives mixed signals from the temperature receptors. As a result, the brain interprets the mixed signals as both hands feeling warm. Therefore, the correct statement is that both the right and left hands feel warm.

      Reamur

    • D.

      Kelvin

    Correct Answer
    A. Fahrenheit
    Explanation
    In the European country of England, the temperature is measured using the Fahrenheit scale for weather reports.

    Perbandingan skala termometer berikut ini yang benar adalah ....

    • A.

      C : R = 4 : 5

    • B.

      C : F = 5 : 9

    • C.

      R : F = 9 : 4

    • D.

      C : (F-32) : 5 : 9

    Correct Answer
    D. C : (F-32) : 5 : 9
    Explanation
    The correct answer is C : (F-32) : 5 : 9. This is the correct comparison of the Celsius (C) and Fahrenheit (F) scales. It shows that the ratio between the Celsius scale and the Fahrenheit scale is (F-32) : 5 : 9, indicating that to convert from Celsius to Fahrenheit, you need to subtract 32 from the Fahrenheit temperature and then multiply it by 5/9.

  • 7. 

    Suhu  100 derajat celcius sama dengan ... .

    • A.

      60 derajat reamur

    • B.

      212 derajat fahrenheit

    • C.

      273 K

    • D.

      0 K

    Correct Answer
    B. 212 derajat fahrenheit
    Explanation
    The correct answer is 212 degrees Fahrenheit. This is because 100 degrees Celsius is equal to 212 degrees Fahrenheit according to the conversion formula.

  • 8. 

    Suhu benda  40 derajat celsius sama dengan .....

    • A.

      24 derajat reamur

    • B.

      32 derajat reamur

    • C.

      48 derajat reamur

    • D.

      50 derajat reamur

    Correct Answer
    B. 32 derajat reamur
    Explanation
    The correct answer is 32 degrees Reamur. This is because the conversion formula from Celsius to Reamur is R = C × 4/5. Therefore, when the temperature is 40 degrees Celsius, it can be converted to Reamur by multiplying it by 4/5, which equals 32 degrees Reamur.

    • D.

      Alkohol dan bimetal

    Correct Answer
    A. Air raksa dan alkohol
    Explanation
    The correct answer is air raksa dan alkohol. Air raksa and alkohol are used as the liquid substances in a maximum-minimum thermometer. Air raksa is used to measure the maximum temperature, as it expands when heated. Alkohol is used to measure the minimum temperature, as it contracts when cooled. By using both substances, the thermometer can accurately measure and display both the highest and lowest temperatures reached.
